Liquid-phase tuning of porous PVDF-TrFE film on flexible substrate for energy harvesting

Flexible substrate electrostatic energy harvester

Energy harvesting is attractive for powering wireless sensors, especially in applications such as body sensor networks and pervasive sensing, where power source replacement or recharging is impractical. A MEMS (micro-electro-mechanical systems) electrostatic harvesting device suitable for body motion has been reported previously, using a rolling rod as the proof mass. A new rolling rod device i...

Multifunctional Flexible PVDF-TrFE/BaTiO3 Based Tactile Sensor for Touch and Temperature Monitoring

This paper presents an enhanced piezoelectricity based sensor for touch and temperature sensing. The sensor is realized over flexible polyimide film, making it suitable for application like e-skin. The sensing material is composed of Polyvinylidene Fluoride-Trifluoroethylene (PVDF-TrFE) and Barium Titanate (BaTiO3) nanoparticles. While, the piezoelectric polymer PVDF-TrFE ensures the flexibilit...

Models for 31-Mode PVDF Energy Harvester for Wearable Applications

Currently, wearable electronics are increasingly widely used, leading to an increasing need of portable power supply. As a clean and renewable power source, piezoelectric energy harvester can transfer mechanical energy into electric energy directly, and the energy harvester based on polyvinylidene difluoride (PVDF) operating in 31-mode is appropriate to harvest energy from human motion. This pa...

Simulation and experimental modeling of a multipoles variable capacitor for an electrostatic wind energy harvester

The aim of this work is to study the effect of rotational motion generated by wind on the capacitance variation of the multipole variable capacitor. AutoCAD software was used to model the variable capacitor and to calculate the capacitance variation relative to the angular position caused by wind. Subsequently, experiments were carried out to measure the capacitance variation relative to the an...
